beast of outlandisher size

[Tellus]

@Euphemism

I cannot find anywhere in the core rulebook where these supposed guidelines for increasing the size of living targets are, that the errata refers to.

Any help would be greatly appreciated.

ArM5 (Corebook), p. 192, top of first column:

An increase or decrease of three points of Size is approximately equal to a factor of ten change in size.

... this should maybe also go on the list of 'hard to find rules'
